Thanks for the comments Chris, Alex, Ryan, and Martin.
Martin, I will post a few two at a time. All taken 7 or 8 yrs ago using the same gear and almost exactly the same procedure.
8" f/5 Newt-- 30 or 45 sec subs [depending on the polar alignment on the
particular night]. ISO 1600 [the sweet spot for the camera]. Canon unmodded
1100D. In camera long exposure noise reduction set to strong, and high ISO
noise reduction enabled, therefore no separate darks, no flats or biases.
No filters, and unfortunately no coma corrector at that time.
All stacking and processing [such as it was] carried out in DSS except for a
little sharpening and downsizing for posting here in PS.
I had been APing for about 50 yrs when the digital age arrived, so being
70+ and nearly computer illiterate I opted to stick to basics.
First ones M83 and NGC 1365
cheers raymo
